Loyalty programs aren't what they were five years ago. Airlines have restructured earning, tightened redemptions, and tied elite status ever more tightly to dollars spent rather than miles flown. But the best programs still deliver real value — if you're aligned with the right one for how and where you actually travel. Here's where things stand in May 2026, with a specific lens on what works for flyers out of SMF.

Alaska Atmos Rewards — the unified loyalty program that replaced Mileage Plan in late 2025, combining Alaska Airlines, Hawaiian Airlines, and Horizon Air — continues to lead for Sacramento-based travelers, and it's not particularly close. NerdWallet named Atmos Rewards its "Best Airline Rewards Program" for 2026. Alaska operates a robust nonstop network out of SMF — including routes to Seattle (SEA), Portland (PDX), Los Angeles (LAX), and a growing slate of leisure destinations — and its partner award chart is still one of the most generous in the industry. You can redeem Atmos points on American, British Airways, Cathay Pacific, Finnair, and Japan Airlines, among others, which gives you outsized international value from a regional earning base.
Elite status through Atmos Rewards is also more attainable and flexible than United or Delta equivalents. Status is earned via status points — accumulated through miles flown (1 pt/mile), dollars spent (5 pts/$), or segments flown — meaning you can mix and match methods to hit Gold (roughly 40,000–50,000 status points) rather than being locked into a single spend-heavy metric. The perks — complimentary upgrades, lounge access on international itineraries, and a $99 companion fare now valid on all North American Alaska and Hawaiian flights — still feel meaningful rather than cosmetic.
Here's a deal we found in April from SMF to New York. This deal probably would cost you 25,000 points round-trip according to the current Atmos program details (12,500 points per one-way in economy for distances over 2,101 miles — SMF to JFK clocks in at roughly 2,590 miles).
United MileagePlus is the strongest play if your goal is international travel. United operates the most transatlantic and transpacific routes of any carrier with SMF connections through its San Francisco (SFO) hub, and MileagePlus miles transfer from Chase Ultimate Rewards at a 1:1 ratio — making them easier to accumulate than airline-issued miles alone.
The program shifted to dynamic pricing in 2024, which cut into the ceiling of premium cabin deals, but United's Saver awards — when available — still represent solid value on Star Alliance partners including Lufthansa, ANA, and Singapore Airlines. If you hold a Chase Sapphire Reserve or Chase Sapphire Preferred, MileagePlus is a natural home for your points.
After a bruising public backlash in late 2023 over SkyMiles devaluation, Delta SkyMiles walked back some of its most aggressive changes and restored Amex card benefits. SkyMiles has stabilized, and Delta's SMF presence — including nonstop service to Atlanta (ATL) and Salt Lake City (SLC) — gives loyalty points a runway to accumulate.
The program's weakness remains unpredictable award pricing. Delta uses fully dynamic pricing with no published chart, meaning the same itinerary can cost wildly different amounts depending on timing. Use SkyMiles if Delta is your default carrier at SMF, but don't build your entire strategy around it.
Southwest Rapid Rewards doesn't have a traditional award chart, which frustrates miles optimizers — but for the average SMF traveler, it's quietly one of the most practical programs available. Points are worth approximately 1.3–1.5 cents each (per TPG and NerdWallet 2025–2026 valuations), though actual value varies by redemption due to dynamic pricing — there are no change or cancellation fees, and the Companion Pass — earned after 135,000 qualifying points in a calendar year — is one of the most valuable perks in all of domestic travel.
Southwest's SMF service covers key leisure markets including Las Vegas (LAS), Phoenix (PHX), Denver (DEN), and Hawaii with seasonal frequency. If you primarily fly domestically and value flexibility over first-class aspirations, Rapid Rewards earns its place in your wallet.
Alaska Atmos Rewards is the strongest overall program for SMF-based flyers, thanks to Alaska's nonstop network out of Sacramento, flexible elite status earning (by miles, spend, or segments), and a partner award chart that includes American, British Airways, and Japan Airlines. United MileagePlus is the better choice if international travel is a priority.
Yes. Chase Ultimate Rewards transfer 1:1 to United MileagePlus, Southwest Rapid Rewards, British Airways Avios, Air Canada Aeroplan, and several other programs. This makes Chase cards a flexible hub for accumulating miles without flying a single segment.
Yes — the Companion Pass remains one of the highest-value perks in domestic travel. Once earned, a designated companion flies with you on any Southwest flight for only the cost of taxes and fees, for the remainder of the calendar year in which you earn it plus the entire following year.
Partially. Delta reversed some of the most unpopular changes, particularly around Amex card benefits and lounge access thresholds. SkyMiles is more usable than it was at the height of the backlash, but dynamic award pricing without a published chart still makes it harder to plan redemptions compared to Alaska or United.
